Android fixes 129 security flaws in major phone update
NEWYou can now listen to Fox News articles!
Most people never think about Android security updates until a headline like this appears. Suddenly, your phone, the device you use for messages, banking, photos and work, becomes part of a global cybersecurity story.
That is exactly what happened this week. Google released its latest Android security updates, and they fix a massive 129 vulnerabilities. Even more concerning, one of them is already being exploited by attackers.
The flaw targets a component connected to Qualcomm graphics hardware, and researchers say it has already been used in limited targeted attacks. If you use an Android phone, this is the kind of update you want installed as soon as possible.

Android security flaw already targeted by attackers
One vulnerability in particular has security researchers paying close attention. The flaw is tracked as CVE-2026-21385. Google says there are signs it is already being used in targeted attacks. That makes it a zero-day vulnerability.
In simple terms, attackers discovered the flaw before many devices received a fix. According to Qualcomm, the problem is tied to the graphics processing component inside many of its chipsets. Specifically, the issue involves something called an integer overflow. That technical term means a calculation error can cause memory corruption inside the system. Once that happens, attackers may gain a foothold on the device.
Qualcomm says the flaw impacts 235 different chipsets, which means a large number of Android phones could be affected. Google’s Threat Analysis Group discovered the issue and reported it through coordinated disclosure practices. Qualcomm then worked with device makers to release patches.
Why the Android security vulnerability is dangerous
Several of the patched vulnerabilities allow attackers to execute code remotely or gain elevated privileges on a device. One issue inside the Android System component is especially concerning. Google says it could allow remote code execution without any user interaction.
That means an attacker may exploit the flaw without the victim tapping a link or installing an app. In cybersecurity terms, that type of vulnerability ranks among the most dangerous.
The March Android bulletin addresses ten critical flaws across the System, Framework and Kernel components. These parts sit at the core of Android, so any weakness there can ripple across millions of devices.

Why some Android phones get security updates faster
Google released two patch levels for this update:
- 2026-03-01 security patch level
- 2026-03-05 security patch level
The second update includes everything in the first, plus fixes for additional hardware components and third-party software. Google Pixel devices typically receive updates immediately. However, many Android users must wait longer.
Phone manufacturers such as Samsung, Motorola and OnePlus often test the patches before releasing them for specific models. Carriers may also delay updates while they verify compatibility. As a result, some users receive security patches quickly while others wait weeks.
How to protect your Android phone from security threats
Security vulnerabilities are a reality in modern software. The good news is that there are several simple steps that can greatly reduce your risk.
1) Install Android updates quickly
Check for updates regularly and install them as soon as they appear. On most devices, go to Settings, tap Security and privacy or Software update, then select Check for updates and install the latest version if one is available. Security updates often fix vulnerabilities that attackers may already be trying to exploit.
2) Avoid apps from unknown sources
Only download apps from trusted stores like Google Play. Third-party app stores pose a higher risk of malware.
3) Keep Google Play Protect enabled
Google Play Protect, which is built-in malware protection for Android devices, scans apps for malicious behavior and warns you if something suspicious appears. It also automatically removes known malware. However, it is important to note that Google Play Protect may not be enough. Historically, it isn’t 100% foolproof at removing all known malware from Android devices. Therefore, we recommend strong antivirus software because it adds another layer of protection by using deeper threat detection, real-time monitoring and broader malware databases that can catch suspicious apps or files that Google Play Protect may overlook.

4) Use strong device security
Set a strong passcode on your phone and turn on fingerprint or face unlock if your device supports it. This helps keep strangers out of your phone if it is lost or stolen.
5) Be cautious with suspicious links
Many attacks still start with phishing messages. Avoid tapping unknown links in texts, emails, or social media messages.

The bigger picture behind Android security updates
This Android update also highlights how modern mobile security works behind the scenes. Google’s Threat Analysis Group frequently discovers vulnerabilities that may already be used in real-world attacks. Those findings trigger coordinated responses involving chip manufacturers, phone makers and security researchers. In this case, Qualcomm received the report in December and provided fixes to device makers in early 2026.
By the time the public bulletin arrived, patches were already moving through the Android ecosystem. The process may look slow from the outside. In reality, it involves dozens of companies working together to prevent widespread exploitation.
Kurt’s key takeaways
Security updates rarely feel exciting. Yet they play a critical role in protecting billions of smartphones around the world. This latest Android update proves that point clearly. A zero-day flaw tied to Qualcomm graphics hardware was already being targeted before many users even knew it existed. Installing updates quickly remains one of the simplest ways to protect your device and your personal data. Most of the time, the update only takes a few minutes. Those few minutes can block attacks that might otherwise compromise your phone. So the next time your Android device prompts you to install a security patch, the better question may be this:
When your phone asks for a security update, do you install it immediately or tap remind me later? Let us know by writing to us at Cyberguy.com

Valve is so behind on Steam Controller orders that some won’t ship until 2027
Valve has some good news and bad news about Steam Controllers. The good news: if you make a reservation for a Steam Controller, the company will now show you one of three estimates of when you’ll be able to actually order your gamepad: by September 2026, by December 2026, or sometime in 2027. The bad news: any reservations made today “indicate a 2027 date for shipping,” Valve says.
“We have no plans to stop making Steam Controller,” according to Valve. “But as we look at the current demand compared to how many we know we can make by the end of the year, we want to manage expectations as much as we can with regards to when folks can expect to receive their order.”
Valve’s very good new Steam Controller went on sale in early May, and the initial rush led some people to run into frustrating problems with trying to check out ahead of the controllers eventually going out of stock. A few days later, the company announced that it would be implementing a reservations queue for interested buyers so they could get on a waitlist. If you’re on the waitlist, when you get notified that a Steam Controller is ready for you to buy, you have 72 hours to actually make the order.
“When we launched Steam Controller last month, we quickly saw that initial demand exceeded our expectations,” Valve says. “Switching to a reservation queue has (hopefully) cut down on the headaches on the customer side, and for us it’s also been helpful as we plan ahead and try to get as many out as quickly as we are able.”
All three of Valve’s big hardware products were delayed from a planned early 2026 launch because of the component crisis, Valve still hasn’t announced when the Steam Machine PC or Steam Frame VR headset might go on sale. However, just yesterday, Valve officially launched its big SteamOS 3.8 update with support for the Steam Machine. It’s also been importing a lot of hardware into the US as of late.

McDonald’s AI drive-thru may take your next order
NEWYou can now listen to Fox News articles!
The next time you pull up to a McDonald’s drive-thru, the voice taking your order may not be human. McDonald’s is testing a new AI-powered system called ArchIQ at five U.S. locations. The company has not said where those restaurants are located. The voice assistant, nicknamed Archy, can take drive-thru orders and has shown it can handle both English and Spanish.
For anyone who has repeated “no pickles” into a speaker box more than once, this could sound helpful. However, if you remember McDonald’s last AI drive-thru experiment, you may also wonder whether your burger order could somehow turn into a bag full of surprise McNuggets.

WOULD YOU EAT AT A RESTAURANT RUN BY AI?

What is McDonald’s AI drive-thru?
ArchIQ is McDonald’s new AI system for restaurants. It can take drive-thru orders and also help with operations behind the scenes.
In a post on X, McFranchisee, an anonymous McDonald’s franchisee account, said the system is currently in five test stores and has processed more than one million transactions. The account also said about 90% of orders were completed without a human stepping in. That number sounds promising. Still, McDonald’s has not confirmed a nationwide launch date. For now, this remains a limited test.
The system also appears to connect with a bigger McDonald’s plan called “McDonald’s > NEXT.” CEO Chris Kempczinski described the strategy as a way to bring in more customers and improve restaurant productivity. The plan also includes menu changes, restaurant redesigns, technology upgrades and more focus on hospitality.
Why McDonald’s is testing AI ordering
Drive-thrus can get chaotic fast. Someone changes an order after the total appears. A child calls out from the back seat. Road noise makes the speaker hard to hear. Then the driver remembers the extra sauce after everything has already gone through. That is the type of pressure McDonald’s wants AI to handle.
If ArchIQ works well, it could help restaurants move cars through the line faster. It may also reduce mistakes during busy hours. Workers could then focus more on preparing food, handling payments and helping customers who need a real person.
ArchIQ also appears to have a management role. In the same X post, McFranchisee described Archy as a tool that could alert managers to bottlenecks or other issues before they slow down operations.

McDonald’s tried AI drive-thru ordering before
This new test follows McDonald’s earlier AI drive-thru experiment with IBM. That program involved more than 100 restaurants. McDonald’s ended the test in 2024 after customers complained about order accuracy. Some mistakes also went viral, creating an embarrassing moment for McDonald’s and raising questions about whether the technology was ready for the drive-thru. Customers reported wrong items, strange quantities and other order mix-ups. That history is why this new test will get extra attention.
This time, McDonald’s is working with Google technology. McFranchisee also claimed every McDonald’s in the U.S. is getting Google Edge Cloud hardware in anticipation of the rollout. McDonald’s seems to believe the newer system can perform better than the last one. The real test will come when regular customers use it during real drive-thru rushes.
How McDonald’s AI drive-thru could help customers
If McDonald’s gets this right, the most obvious benefit is speed. An AI ordering system does not get tired during a long shift. It may also help more customers order in the language they prefer. That could make a busy drive-thru feel less frustrating, especially during breakfast or late-night hours.
The system may also ask clearer follow-up questions and catch missing details before the order reaches the kitchen. That would be a win for customers who want to get in, get their food and get on with the day.
The biggest problem with AI drive-thru orders
The biggest concern is accuracy. AI can still misunderstand people. That gets frustrating fast when you are trying to grab lunch between errands or get your kids fed from the back seat. A wrong order wastes time. It also puts workers in the position of fixing a mistake the machine made.
There is also the customer service side. Some people like hearing a real person at the speaker. Others may find an AI voice cold or annoying, especially if the system gets confused.
Then there is the privacy question. If an AI system takes your order, customers may wonder what gets collected, how long it is kept and who can access it. McDonald’s has not publicly explained those specifics for this current ArchIQ test.
ALEXA+ LETS YOU ORDER FOOD LIKE A REAL CONVERSATION

How to avoid AI drive-thru mistakes
Before you leave the drive-thru, take a moment to check the order screen. Make sure the items match what you said. Listen when the system repeats your order. Keep your receipt until you confirm the food is right.
Also, avoid sharing extra personal details at the speaker box. Your order should only require your food choices and payment.
If the AI gets confused, ask for a crew member. You do not need to keep going back and forth with a machine over fries.
What this means for you
For now, you probably will not notice a change at your local McDonald’s. The ArchIQ test appears limited to five U.S. restaurants, and the company has not said when it could expand.
Still, this gives customers a preview of where fast food may be heading. AI could soon play a bigger role in how restaurants take orders and manage the kitchen. That may speed up the line, though it could also make the experience feel less personal.

Kurt’s key takeaways
McDonald’s clearly wants AI to play a bigger role in its restaurants. From a business point of view, the idea makes sense. Shorter drive-thru lines could help franchisees and customers. Better restaurant data could also help managers fix problems faster. But I still want the human backup. Food orders can be messy because people are messy. We change our minds. We talk over each other. We forget the extra ketchup until the last second. AI may handle much of that one day. For now, I would treat it like any busy drive-thru interaction. Speak clearly. Check the order. Do not pull away until you know your food is right.

Midjourney goes from generating cat images to full-body ultrasound scans
Midjourney CEO David Holz just showed off the company’s first hardware product and plans to build a San Francisco spa, which he admitted is a bit different from the “cat pictures” produced by its AI image generator. Dubbed The Midjourney Scanner, it’s an ultrasound-based full-body scanner that uses a ring of sensors to capture vertical slices of the inside of your body, looking at the composition of your muscle, fat, bone, and organs to start. Holz said ideally, you could do this once a year or every single day, as it “aims for image quality comparable to MRI in many ways.”
He mentioned that one way he’d like to use it would be to see how his body changes in response to diet and workout changes, saying, “I’m not the most measured man on Earth yet, you know, but maybe I want to have that daily [measurable information].” A set of job listings advertises the company’s goal as trying to “build and launch the world’s first full-body ultrasound CT scanner, ultimately bringing safe, fast, and high fidelity preventative scanning to billions via a magical spa experience.”
The Midjourney Scanner was developed in a partnership with ultrasound tech company Butterfly Network, which said it uses “40 Butterfly Ultrasound-on-Chip imaging modules per system.”
The scanning process starts with stepping onto a platform that drops down into the water on rails through a ring of thousands of transducers that create ultrasonic waves. It then records the ripples passing through your body to analyze them and create detailed 3D images. The scan takes about 60 seconds. Holz said about a dozen people have been scanned so far.
It starts by stepping into a shallow pool of golden light. You then begin to descend into the water. Your body passes through a ring of underwater sensors, each acting like a dolphin, using its echolocation. The sensors send ultrasonic sound waves through your body from every angle. With enough waves, and enough angles, we form an image of what’s happening inside your body.
It combines those sensors with two petaflops of processing power. But after watching the livestreamed reveal, I’m still unclear on what Midjourney’s AI image generation tech exactly has to do with the Midjourney Medical effort, beyond an alternative business for otherwise-unused AI compute.
Holz hopes to put 10 of the scanners into a Midjourney Spa location in San Francisco’s Union Square that will open before the end of 2027 and offered to scan the hands of attendees at its launch event. The Midjourney Spa will have a gym, saunas, and cold plunges to go along with the hot tub–equipped scanning rooms where visitors will get into the water to be scanned.
He did mention that various medical applications would require FDA clearances, but for now, Midjourney Medical says it’s working on “body composition maps” that don’t require the same level of clearance as diagnostic imaging. It also says the “library of scans” users create can be shared with doctors, AI health tools, or others, and that, “We take data privacy seriously — more details on our data policies will come as we get closer to launch.”
Holz suggested that eventually these scans could become better than an MRI, without radiation, powerful magnets, or other complicating factors, to get a look at what’s going on inside people’s bodies “real fast.” In response to a question, he imagined a future where the FDA had a class of devices to look at “weird” things and allowed people to “just try to get as much data as we can.”
